<h2 id="cdr">C defect report implementation status</h2>

<p>This page tracks which C defect reports are implemented within Clang.</p>

<p>The implementation status for defect reports against the C Standard are
currently under investigation. Any defect report whose status in Clang is
currently unknown will be marked in <span class="unknown">magenta</span>.</p>

<p>The <a href="https://github.com/llvm/llvm-project/issues/">LLVM bug tracker</a> uses
the "c", "c99", "c11", "c17", and "c2x" labels to track known bugs with Clang's language
conformance.</p>
